No it's not necessary! The crank doesn't rotate when you pulling in with the tool.
First step you screw the M20 bolt onto the crank by rotating it like a simple nut. After that the bolt is connected to the crank.
When you turn right the nut on the M20 screw you need to dolly the bolt's head with another wrench, so the crank and the bolt is not turning!
Maybe Martin's tool works different way, but my personakl opinion is that one is needlessly complicate. It's also not very good if you rotate it with a lefthanded tool because the crank's thread have an "active role" (radial forces on the thread).
I am NOT saying Martin's tool is bad, it's also great but the other tool protect the crank's thread more!
If you still not understand I will take some photoes.
